The design and manufacture of pharmaceutical tablets is a complex multi-stage process whereby formulation scientists ensure that the correct amount of drug substance in the right form is delivered at the appropriate time at the proper rate and in the desired location with its chemical integrity protected to that point Most drug substances do not possess the required properties which give
The double roller granulator (granulator-compactor) uses an auger-feed system that will consistently deliver powder uniformly between two pressure rollers The powders are compacted into a ribbon or small pellets between these rollers and milled through a low-shear mill When the product is compacted properly it can then be passed through a mill and final blend before tablet compression
Many types of refining mills have been used to improve sugar yields including disk ball PFI and roller (Szego) mills as well as extruders However it is hard to choose the best type of mill because biomass structure types of hydrothermal/chemical pretreatment and milling conditions affect overall sugar yields For example in the case of sodium carbonate-pretreated hardwood chips
